Abstract

The invention discloses a composite material prepared from active carbon and used for adsorption. The composite material comprises, by weight, 15-25 parts of an adhesive, 4-8 parts of a transition metal compound, 8-16 parts of a carbon nitride compound, 10-16 parts of active carbon, 3-7 parts of nickel nitrate and 2-8 parts of tetrabutyl titanate. The composite material has the advantages of good purification effect and substantial use effects.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a composite material prepared by activated carbon for adsorption. Background technique [0002] my country is currently one of the 13 countries with the poorest water in the world. According to the latest "China Environmental Performance Evaluation" report released by the Organization for Economic Cooperation and Development, more than 75% of the water flowing through Chinese cities is not suitable for drinking, and more than 30% The water quality of the detected river belongs to the inferior V category. With the development of industry, the degree of pollution of urban drinking water sources is increasing. At the same time, with the improvement of living standards, people's requirements for drinking water quality and drinking water quality standards are becoming more and more stringent. [0003] The activated carbon materials currently on the market for water treatment mainly use ...
